Aim: The aim of the present paper is two-fold. First, it reviews the Hippocratic collection to identify instances related to the issue of medical malpractice and medical negligence. Second, it discusses the results viewed from today's perspective, in the context of contemporary theories of liability in malpractice cases. Method: A careful review of the books of Hippocratic collection was performed, as well as a narrative review of the currently available academic literature, focusing on topics of contemporary theories of liability in malpractice cases, which correspond roughly to the medical malpractice instances identified in Hippocratic collection. Results: The Hippocratic authors touch on some issues which are essential to the contemporary theory of medical error and negligence, which, however, cannot yet unquestionably address these issues. Among others, they refer to errors that contemporarily might be viewed as technical human errors, errors of omission, or errors which were unavoidable in the context of applied ancient Greek medicine as is the case of injuries that are not based on physician's fault, or situations where the diagnosis of the particular disease or causal link between the physician's breach of duty and the damage suffered, was difficult or even impossible. Interestingly, the Hippocratic authors underscore some errors which might not be based on physician's fault. Conclusion: The passages mentioned in this paper, originating from the Hippocratic collection that refer to medical malpractice, imply an awareness of what is currently discussed as medical malpractice. This consideration may carry some weight, in particular when adopting a flexible traditionalist approach to the medical liability rules. [ABSTRACT FROM AUTHOR]

Objectives: The economic crisis and the resulting austerity in Greece led to a drastic reduction in healthcare spending, which has been assumed to have impacted people's health. This paper discusses official standardized mortality rates in Greece between 2000 and 2015. Methods: This study was designed to analyze population-level data and collected data from the World Bank, the Organisation for Economic Co-operation and Development, Eurostat, and the Hellenic Statistics Authority. Separate linear regression models were developed for the periods before and after the crisis and were compared. Results: Standardized mortality rates do not support a previously reported assumption of a specific and direct negative effect of austerity on global mortality. Standardized rates continued to decrease linearly, and their correlation to economic variables changed after 2009. Total infant mortality rates show an overall rising trend since 2009, but the interpretation is unclear because of the reduction in the absolute number of deliveries. Conclusions: The mortality data from the first six years of the financial crisis in Greece and the decade that preceded do not support the assumption that budget cuts in health are related to the dramatic worsening of the overall health of the Greek people. Still, data suggest an increase in specific causes of death and the burden on a dysfunctional and unprepared health system that is working in an overstretched manner trying to meet needs. The dramatic acceleration of the aging of the population constitutes a specific challenge for the health system. [ABSTRACT FROM AUTHOR]

Introduction: Fiscal federalism and fiscal decentralization are distinct policy options in public services in general and healthcare in particular, with possibly opposed effects on equity, effectiveness, and efficiency. However, the pertinent discourse often reflects confusion between the concepts or conflation thereof. Methods: This paper performs a narrative review of theoretical literature on decentralization. The study offers clear definitions of the concepts of fiscal federalism and fiscal decentralization and provides an overview of the potential implications of each policy for healthcare systems. Results: The interpretation of the literature identified three different dimensions of decentralization: political, administrative, economic. Economic decentralization can be further implemented through two different policy options: fiscal federalism and fiscal decentralization. Fiscal federalism is the transfer of spending authority of a centrally pooled public health budget to local governments or authorities. Countries like the UK, Cuba, Denmark, and Brazil mostly rely on fiscal federalism mechanisms for healthcare financing. Fiscal decentralization consists of transferring both pooling and spending responsibilities from the central government to local authorities. Contrarily to fiscal federalism, the implementation of fiscal decentralization requires as a precondition the fragmentation of the national pool into many local pools. The restructuring of the pooling system may limit the cross-subsidization effect between high- and low-income groups and areas that a central pool guarantees; thus, severely affecting local equality and equity. With the limited availability of local public resources in poorer regions, the quality of services drops, increasing the disparity gap between areas. Evidence from Italy, Spain, China, and Ivory Coast -countries with a strong fiscal decentralization element in their healthcare services-suggests that fiscal decentralization has positive effects on the infant mortality rate. However, it decreases healthcare resources as well as access to services, fostering spatial inequities. Conclusion: If public resources are and remain adequate, allocation follows equitable criteria, and local communities are involved in the decision-making debate, fiscal federalism -rather than fiscal decentralization-appear to be an adequate policy option to improve the healthcare services and population's health nationwide and achieve health sector economic decentralization.

Aim: The aim of the current study was to evaluate the level of the basic knowledge of the Turkish gynecologists regarding electrosurgery. Materials and Methods: A survey was undertaken to evaluate the level of basic knowledge and attitudes regarding electrosurgery use among gynecology specialists and residents. The questionnaire used comprised of two parts: a) questions evaluating the participants' professional experience, whether they had received formal electrosurgery training, and their course of action concerning the use and safety precautions of the electrosurgery unit, and b) questions designed to evaluate the knowledge level of the participants on the basic electrosurgical principles. Results: One hundred seventy-three gynecologists were included in the study and their mean knowledge score was 49.1 %. No difference was detected between the mean scores of specialists and residents. The mean score of participants who had read articles/papers on electrosurgery was significantly higher compared with uninformed participants (p =0.001). The mean score of participants who had previously attended electrosurgery training seminars was significantly higher compared with participants who had not attended seminars (p =0.013). Conclusion: Gynecologists in Turkey do not have sufficient basic knowledge regarding the reliable and efficient use of electrosurgery. [ABSTRACT FROM AUTHOR]

Background: Serous adenocarcinoma is the most common subtype of ovarian carcinoma, while ovarian echinococcosis is a rare disease of the female genital system. The simultaneous presence of adenocarcinoma and echinococcosis in the same ovary is extremely rare and little data exist regarding diagnosis and treatment approach. Materials and Methods: In the present paper, we report a rare case of a 66-year-old Greek Caucasian woman of rural origin, with an adnexal mass, ascitic and pleural fluid. The patient underwent exploratory laparotomy following neoadjuvant chemotherapy, based on positive for malignancy pleural and ascitic fluid cytology results. Results: Histological examination of the surgical specimen indicated the synchronous presence of echinococcosis and adenocarcinoma in the same ovary. Conclusions: Ovarian hydatid cyst is extremely rare, but should be suspected in patients with echinococcosis in other organs and those coming from endemic areas. Moreover, the disease could mimic ovarian cancer, as there are no specific symptoms and clinical signs. The coexistence of these two diseases in the same ovary, although rare, is possible. It seems that the presence of the hydatid cyst does not change the treatment approach of the malignancy so that surgery with neoadjuvant or adjuvant chemotherapy, according to the present guidelines, should be administered.

Alport syndrome (ATS) results from X-linked, COL4A5 mutations (85%) or from autosomal recessive homozygous or compound heterozygous COL4A3/A4 mutations (15%), associated with alternate thinning and thickening as well as splitting and lamellation of the glomerular basement membranes. In contrast, familial microhematuria with thin basement membranes is thought to result from heterozygous COL4A3/A4 mutations. This absolute separation may not always be true. Renal biopsies and molecular genetics were used to study microhematuric families in the Hellenic population we serve. The COL4A5 gene was studied by PCR and direct re-sequencing for new mutations, while PCR-RFLP was used to identify more carriers of known COL4A5 and COL4A3/A4 mutations. Molecular genetics in two undiagnosed microhematuric Cypriot families, revealed COL4A5 mutation P628L indicating X-linked ATS. Of nine males, seven developed end stage kidney disease (ESKD) between 31 and 56, while two are well at 51 and 57, exhibiting microhematuria and thin basement membrane nephropathy (TBMN). COL4A5 mutation G624D was also identified in six Greek families. Seventy five members had DNA tests and 37 proved positive. Four positive males developed ESKD at 61, 51, 50 and 39 years, while the remaining and all females showed only microhematuria. A literature search revealed eight papers with six similar hypomorphic COL4A5 mutations presenting as phenocopies of TBMN. In conclusion, X-linked COL4A5 ATS mutations produce a phenotypic spectrum with a) classical ATS with early onset ESKD, neurosensory deafness and ocular defects b) males with only ESKD and late deafness and c) males due to missense mutations, such as G624D and P628L that may only exhibit microhematuria, TBMN, mild chronic renal failure (CRF) or late onset ESKD. Consequently when investigating "benign familial hematuria" these and other similar X-linked COL4A5 mutations should also be searched for. [ABSTRACT FROM AUTHOR]

The European Union (EU) and the world are faced with unprecedented economic challenges, which if allowed to persist could threaten its continued existence in its current form as a union. Furthermore, these same financial challenges can easily translate into societal hardship. The biomedical and pharmaceutical industries of the U.S. and Europe have been in the midst of severe financial constraints over the last few years, which will worsen in the coming years. A critical factor is a financial crisis that appears to be spreading like wildfire through Europe, with 3 of its oldest members (Greece, Ireland, Portugal) already having enlisted the aid of the International Monetary Fund (IMF) to avoid bankruptcy, and with the possibility of others to follow (Italy, Spain). Adding to this the increasing cost of introducing new medications and devices, and conducting clinical research, as well as the tightening regulatory pressures and the drying pharmaceutical pipelines, cost cutting pressures are mounting on pharmaceutical industries and the biomedical sector, whether in academia or in industry. This paper will attempt to highlight some of the problems that clinical research in Europe may be facing, as well as discuss some of the potential solutions. Although this will by no means be an exhaustive analysis, the goal is to show that times of financial hardship, such as the current one, may also provide the impetus for constructive change.

Introduction: Despite the major advances made in the diagnosis and management of ectopic pregnancies in the last two decades, an accurate diagnosis can sometimes still be quite challenging, since it relies on the combination of ultrasound findings and serial serum beta-human chorionic gonadotrophin (β-hCG) measurements. Case presentation: This paper describes the case of a 36-year-old woman of Caucasian origin who was admitted to the emergency department of our clinic with clinical symptoms of hemorrhagic shock in combination with two negative pregnancy tests done by her at home and a negative urine test which was performed on her admission to the hospital. Quantitative measurement of β-hCG in the serum of the patient was 13 mIU/mL. On admission, right tubal pregnancy was diagnosed on ultrasound and she underwent an emergency laparotomy due to signs of hemodynamic shock. Conclusion: It is sometimes a considerable challenge to identify a patient with an ectopic pregnancy at risk of rupture. This case of ectopic pregnancy which was followed by a negative pregnancy test illustrates the magnitude of the difficulties involved in the diagnosis of ectopic pregnancy. It also demonstrates the need to maintain a high clinical index of suspicion and to undertake careful clinical examination of the patient on the basis of the clinician's diagnostic research.

Breast lymphoma is a rare condition, both as a primary and a metastatic manifestation. The primary form has an incidence ranging from 0.04% to 0.5% of all breast neoplasms, whereas the metastatic form has an incidence of 0.07%. We hereby report a clinical case of a patient who presented with cutaneous non-Hodgkin lymphoma (NHL) in the left scapulohumeral region treated with surgery followed by radiotherapy (40 Gy total). Three years following radiotherapy, the patient was diagnosed with a left breast infiltrating ductal carcinoma, treated with conservative surgery and adjuvant therapy. The following year, i.e. four years after the initial diagnosis of NHL, two lymphoproliferative relapses occurred: in the left cutaneous scapulohumeral region at the original site of disease, and in the right breast. The aim of this paper is to highlight an uncommon oncologic disorder such as breast lymphoma, highlighting its clinical and radiological manifestations. Some studies reported a possible aetiological role of radiotherapy in the development of breast cancer following treatment of NHL, and in the development of breast cancer following treatment of Hodgkin lymphoma, which could potentially explain our findings.

The case on contact shots from firearms with a flash suppressor is rare. When a rifle fitted with a flash suppressor is fired, the emerging soot-laden gas in the barrel escapes from the slits of the flash suppressor. If the shot is contact or near contact, the flash suppressor will produce a characteristic "flower-like" pattern of seared, blackened zones around the entrance. This paper presents the injury pattern of the flash suppressor in a 29-year-old man who committed suicide with a G3 automatic infantry rifle. [ABSTRACT FROM AUTHOR]

Background: Births from adolescent mothers account globally for 10 % of all births and 23 % of maternal morbidity and mortality. Adolescence is a period of rapid biological changes; therefore, teens have a risk of developing iron deficiency anemia. The present study aimed to determine the hematological profile and compare the distribution and the severity of anemia among pregnant adolescents (12-19 years old) over ten years in Northern Greece., Material and Methods: We conducted a retrospective study of pregnant adolescents' medical records and laboratory data recorded during their first prenatal consultation. The laboratory workout was performed in the Thalassemia Prevention Unit of the Hippokration Hospital of Thessaloniki, Greece, from 2013 to 2022., Results: Two hundred nine of the adolescents were of Greek Nationality (88.3 %) (86 Greek natives of the general population; 41.1 %, 112 members of the Roma community; 53.5 %, 11 members of the Muslim minority of Thrace; 5.2 %) and 29 (11.6 %) were immigrants from the Balkans, Middle East, and Asia. The mean age (± standard deviation) of the 238 pregnant women in our study's cohort was 16.67 ± 1.67 years, and the majority of them (90 %) were approximately between 15-19 years, and 10 % were between 12-14 years. Half of the cohort were Greek Roma (47 %) and were our study's youngest (15.9 ± 1.3 years old) adolescent pregnant women. All registered pregnant adolescents had abandoned school. Our data shows anemia in 33.6 %, iron deficiency anemia in 28.5 %, and iron deficiency in 54.6% of these pregnant adolescents. Migrants and Roma had the lowest hemoglobin levels in the second and third trimesters of pregnancy, respectively, while we found the lowest ferritin levels in Roma and Muslims of Thrace., Conclusions: Despite existing knowledge regarding adolescent pregnancy prevalence and its adverse effects, it nonetheless remains a socio-medical problem and a matter of concern in our country.

Background: Recent studies have demonstrated an association between a new onset of smell or taste loss and COVID-19. We investigated the prevalence of smell and/or taste loss and the clinical characteristics and recovery in a comprehensive cohort of consecutive patients treated by two COVID-19 reference hospitals and evaluated late persistence of hyposmia., Methods: A retrospective observational questionnaire study was conducted. All consecutive RT-PCR diagnosed patients who had been hospitalized in March-April 2020 in the COVID-19 care wards were contacted, excluding patients with cognitive disorders and severe deconditioning. The patients responded to a survey about the loss of smell and taste, nasal blockage, and rhinorrhea, rated the symptoms' severity from 0 to 4, and reported the recovery of smell and taste with time. Demographic and clinical characteristics were recorded., Results: We contacted 117 patients. Ninety responded to the questionnaire; 38.9 % of them reported olfactory and 36.66 % gustatory disorders during their disease. Smell loss prior to other symptoms was reported by 42.86 %, and severe hyposmia/anosmia by 74.28 % of the hyposmic. Among the non-ICU treated patients, 43.75 % reported hyposmia. Only 8.89 % had nasal blockage, and 6.66 % rhinorrhea. Most of the patients (85.71 %) recovered their sense of smell in 3-61 days (median: 17; IQR: 24), but 8.57 % had persistent hyposmia. For one out of four, the olfactory loss lasted longer than a month., Conclusion: Smell and taste loss are highly prevalent and early symptoms in hospitalized COVID-19 patients. The great majority recover their smell, but nearly one out of ten have not recovered in two months.  HIPPOKRATIA 2020, 24(2): 66-71., Competing Interests: The authors declare that there is no conflict of interest related to this paper., (Copyright 2020, Hippokratio General Hospital of Thessaloniki.)

Background: Neutrophil-to-lymphocyte ratio (NLR) has been reported to be a valuable diagnostic tool in the decision-making process for surgical procedures in cases requiring urgent intervention. It was also reported that NLR could be used as an independent predictor of septic shock, hospitalization in the intensive care unit, and death in patients with a liver abscess. This study aimed to investigate the contribution of the NLR, which is a cheap and easily calculable marker, to decisions regarding surgical therapy in patients with intestinal obstruction (IO)., Methods: Ninety-one patients hospitalized with IO were enrolled in this retrospective study. There were two groups: a surgical therapy group and a conservative therapy group. Complete blood count (CBC) parameters and NLR values were statistically evaluated to determine whether there was any difference between the groups., Results: The results obtained from the initial CBC tests were compared between the patients receiving surgical therapy (n =30) and conservative therapy (n =61). There was no statistically significant difference in white blood cell counts between the groups (p =0.225). However, there was a statistically significant difference in NLR values between the patients receiving surgical and conservative therapy (p =0.023)., Conclusion: Similar to previous studies investigating other inflammation criteria, we found that high NLR values were statistically significant in favor of the surgical therapy group in determining the need for surgery in ileus cases. The data obtained in our study demonstrate that the NLR measurement contributes to early decision-making concerning surgical therapy in patients with IO at the time of their initial admission to the emergency department.

Objective: Autoimmune mechanisms are often involved in the pathogenesis of Dilated Cardiomyopathy (DCM) and Th1 immune response against cardiac antigens plays a pivotal role in disease development., Methods: IL-2 receptor (CD4+/CD25+) and cytokines IL-2, IFN-γ, IL-10 were studied in 42 patients (17 with DCM - DCM group, 10 patients with hypertrophic cardiac disease - HCD group, and 15 healthy volunteers - Control group). DCM group was subdivided in: DCM-1 (9 patients with recent disease onset) and DCM-2 (8 patients with chronic DCM). The % CD4+/CD25+ T-lymphocytes were analyzed by double fluorescence flow cytometry both ex vivo and after phytohaemagglutinin (PHA)-cultures with/without 5 and 10 microgr of human cardiac myosin. The cytokines were measured using Enzyme-Linked Immunosorbant Assay (ELISA) method., Results: Ex vivo analysis: In DCM group, CD4+/CD25+ T-cells significantly increased compared to other groups (p<0.05), due exclusively to DCM-2 subgroup (p=0.019). In PHA cultures in DCM-2 subgroup CD4+/CD25+ T-lymphocytes were significantly increased compared to all other groups (p<0.001). The addition of myosin in the cultures of DCM-2 subgroup maintained the same result. In cultures supernatants in DCM-2 subgroup, IL-2 levels were impressively increased compared to DCM-1 subgroup (p=5.91x10-6), HCD and Control groups (p<0.001). Addition of antigen decreased significantly IL-2 levels in DCM-2 subgroup (p=0.01). IFN-γ levels followed the same pattern of alterations. IL-10 levels were significantly increased in both DCM subgroups compared to HCD and Control groups (p<0.05)., Conclusions: Increased peripheral CD4+/CD25+ T-cells found in chronic DCM could be a useful prognostic marker in DCM progress. Increased synthesis of IL-2 and IFN-γ and varying IL-10 levels reflects a Th1 pattern of immune response during chronic disease and implies active cellular immunity process, related to poor prognosis. Thus, analysis of the Th1/Th2 phenotype may be useful in disease monitoring in patients with DCM. This paper is a part of PhD thesis. It has been published at the abstract book of the Acute Cardiac Care congress 2010.

The objectives of this paper are to provide an introduction to meta-analysis and to discuss the rationale for this type of research and other general considerations. Methods used to produce a rigorous meta-analysis are highlighted and some aspects of presentation and interpretation of meta-analysis are discussed.Meta-analysis is a quantitative, formal, epidemiological study design used to systematically assess previous research studies to derive conclusions about that body of research. Outcomes from a meta-analysis may include a more precise estimate of the effect of treatment or risk factor for disease, or other outcomes, than any individual study contributing to the pooled analysis. The examination of variability or heterogeneity in study results is also a critical outcome. The benefits of meta-analysis include a consolidated and quantitative review of a large, and often complex, sometimes apparently conflicting, body of literature. The specification of the outcome and hypotheses that are tested is critical to the conduct of meta-analyses, as is a sensitive literature search. A failure to identify the majority of existing studies can lead to erroneous conclusions; however, there are methods of examining data to identify the potential for studies to be missing; for example, by the use of funnel plots. Rigorously conducted meta-analyses are useful tools in evidence-based medicine. The need to integrate findings from many studies ensures that meta-analytic research is desirable and the large body of research now generated makes the conduct of this research feasible.

With the number of scientific papers published in journals, conference proceedings, and international literature ever increasing, authors and reviewers are not only facilitated with an abundance of information, but unfortunately continuously confronted with risks associated with the erroneous copy of another's material. In parallel, Information Communication Technology (ICT) tools provide to researchers novel and continuously more effective ways to analyze and present their work. Software tools regarding statistical analysis offer scientists the chance to validate their work and enhance the quality of published papers. Moreover, from the reviewers and the editor's perspective, it is now possible to ensure the (text-content) originality of a scientific article with automated software tools for plagiarism detection. In this paper, we provide a step-bystep demonstration of two categories of tools, namely, statistical analysis and plagiarism detection. The aim is not to come up with a specific tool recommendation, but rather to provide useful guidelines on the proper use and efficiency of either category of tools. In the context of this special issue, this paper offers a useful tutorial to specific problems concerned with scientific writing and review discourse. A specific neuroscience experimental case example is utilized to illustrate the young researcher's statistical analysis burden, while a test scenario is purpose-built using open access journal articles to exemplify the use and comparative outputs of seven plagiarism detection software pieces.

Cirrhosis due to chronic hepatitis C is the leading indication for liver transplantation in Europe, United States and Japan. Reinfection after liver transplantation is universal and chronic liver disease develops in at least 70% of patients at 3 years, with an accelerated course compared to the nontransplant setting. These facts underscore the need for a better understanding of hepatitis C infection and the various treatment modalities. This paper attempts a brief review of the scope of the disease, as well as the different treatment modalities, with special emphasis given to orthotopic liver transplantation.

Common Rules for Aviation Safety had been developed under the aegis of the Joint Aviation Authorities in the 1990s. In 2002 the Basic Regulation 1592/2002 was the founding document of a new entity, the European Aviation Safety Agency. Areas of activity were Certification and Maintenance of aircraft. On 18 March the new Basic Regulation 216/2008, repealing the original Basic Regulation was published and applicable from 08 April on. The included Essential Requirements extended the competencies of EASA inter alia to Pilot Licensing and Flight Operations. The future aeromedical requirements will be included as Annex II in another Implementing Regulation on Personnel Licensing. The detailed provisions will be published as guidance material. The proposals for these provisions have been published on 05 June 2008 as NPA 2008- 17c. After public consultation, processing of comments and final adoption the new proposals may be applicable form the second half of 2009 on. A transition period of four year will apply. Whereas the provisions are based on Joint Aviation Requirement-Flight Crew Licensing (JAR-FCL) 3, a new Light Aircraft Pilot Licence (LAPL) project and the details of the associated medical certification regarding general practitioners will be something new in aviation medicine. This paper consists of 6 sections. The introduction outlines the idea of international aviation safety. The second section describes the development of the Joint Aviation Authorities (JAA), the first step to common rules for aviation safety in Europe. The third section encompasses a major change as next step: the foundation of the European Aviation Safety Agency (EASA) and the development of its rules. In the following section provides an outline of the new medical requirements. Section five emphasizes the new concept of a Leisure Pilot Licence. The last section gives an outlook on ongoing rulemaking activities and the opportunities of the public to participate in them.

"Man must rise above Earth to the top of the atmosphere and beyond, for only then will he fully understand the world in which he lives"-Socrates (469-399 BC). The basic driving rationales for human space flight (HSF) are rooted in age-old and persisting dreams. Fascination with the idea of people going into the sky for adventures in other worlds goes back to ancient myths. This paper sheds light onto criticisms of HSF programs, by revisiting their scientific grounds and associated benefits, along with the different types of emerging commercial enterprise. Research from space has lead to a wealth of commercial and societal applications on Earth, building up the case for the so-called "Space Applications Market".

The appeal of online education and distance learning as an educational alternative is ever increasing. To support and accommodate the over-specialized knowledge available by different experts, information technology can be employed to develop virtual distributed pools of autonomous specialized educational modules and provide the mechanisms for retrieving and sharing them. New educational standards such as SCORM and Healthcare LOM enhance this process of sharing by offering qualities like interoperability, accessibility, and reusability, so that learning material remains credible, up-to-date and tracks changes and developments of medical techniques and standards through time. Given that only a few e-learning courses exist in aerospace medicine the material of which may be exchanged among teachers, the aim of this paper is to illustrate the procedure of creating a SCORM compliant course that incorporates notions of recent advances in social web technologies. The course is in accordance with main educational and technological details and is specific to pulmonary disorders in aerospace medicine. As new educational trends place much emphasis in continuing medical education, the expansion of a general practitioner's knowledge in topics such as aviation and aerospace pulmonary disorders for crew and passengers becomes a societal requirement.

Currently, paper-based and/or electronic together with telecommunications links to Earth-based physicians are used to assist astronaut crews perform diagnosis and treatment of medical conditions during space travel. However, these have limitations, especially during long duration missions in which telecommunications to earth-based physicians can be delayed. We describe an experimental technology called GuideView in which clinical guidelines are presented in a structured, interactive, multi-modal format and, in each step, clinical instructions are provided simultaneously in voice, text, pictures video or animations. An example application of the system to diagnosis and treatment of space Decompression Sickness is presented. Astronauts performing space walks from the International Space Station are at risk for decompression sickness because the atmospheric pressure of the Extra-vehicular Activity space- suit is significantly less that that of the interior of the Station.

Severe and prolonged unmitigated SAS and SMS related symptoms have been thoroughly described in Astronauts during adaptation periods for orbital flight and post orbital flight. It has recently been shown that there is a strong correlation between these symptoms most often suffered by astronauts to that of the symptoms of patients suffering from Postural Deficiency Syndrome (PDS) on Earth that have been successfully assessed, diagnosed and treated. International peer-reviewed literature identifies PDS as a trauma induced medical condition which originates from central neural dysregulation of sensory-motor and cognitive controls; these dysfunctions can be accurately identified, measured, and monitored via a specific ocular-vestibular-postural monitoring system along with relevant clinical data. This higher level of understanding is necessary in order to reach the next stage of success for humans living and working in Space. Central sensory-motor and cognitive controls dysfunction underlie symptoms that can adversely impact and reflect alteration of eye-hand coordination, fine tuned dexterity, body positioning in space, space projection and trajectory control, perception of environment/obstacles, orientation in space and time, sensory motor and cognitive aspects of decision making, sensory-motor/cognitive error proneness. All of these factors are necessary for Astronaut's mission capabilities, while both carrying out operations in Space and performing the tasks required during and after re-entry. The objective of this paper is to elucidate how PDS related medical conditions are currently assessed, identified and monitored, and how these methodologies and technologies translate into a potential for better understanding of astronauts' potential incapacitation during space flight operations.

Inflight medical emergencies occur at a rate of 20 to 100 per million passengers, with a death rate of 0.1 to 1 per million. Cardiac, neurologic, and respiratory complaints comprise the more serious emergencies, as defined by aircraft diversion or use of ground-based medical assistance. In this paper, we review changes seen in the resting electrocardiogram in normal individuals exposed to high altitude, alongside important implications for patients with heart diseases in high altitude exposures and the possible effects of high altitude to permanent cardiac pacemakers. Arrhythmias in pilots and public safety are revisited together with the guidelines of the Joint Aviation Requirements (JAR) in Europe. The situation of Military flights is also discussed. Physicians ought to become knowledgeable about the specific medical job standards for their patients when asked to render opinions regarding fitness to fly. A database must be established to obtain prospective data that defines the risk of accidents in patients who are or were being treated for arrhythmias. Current guidelines could then be updated and revised as appropriate.

Biomedical signal monitoring can counteract the risk of human operator error due to inattention or fatigue in safetycritical and restrictive environments, such as in aviation, space, automobile and heavy industrial machinery operation. Real-time biomedical data acquisition is changing through advances in microelectronics fabrication, bio-MEMS and power micro-generators. Such data acquisition and processing systems are becoming increasingly miniaturised, flexible and pervasive, while data is being collected from inside the human body as well as around it. In this paper we review two related research projects exploiting this technological convergence, discuss its implications and suggest future innovation prospects through further similar cross-disciplinary synergies.

The paper introduces "Glottal Disturbogram" as a new tool for the discrimination, evaluation and representation of glottal disturbances which may be met in pathological voicing or singing. The "Glottal Disturbogram's" principles and related features also suit similar applications such as the acoustics of some families of musical instruments. Disturbogram's computational and display characteristics are presented with the use of both synthetic glottal patterns and real signals obtained from subjects with voice disorders. Results show that Disturbogram may efficiently discriminate and quantify perturbation types, offering a valuable tool in clinical or laboratory investigation of both voice disorders and normal voicing types.

In this paper we present a model to evaluate the effect of certain majors socioeconomic factors (such as alcohol and fat consumption, cigarettes smoking, unemployment rate as a proxy for uncertainty which results frustration, number of passenger cars as a proxy for physical exercise and per capita GDP as a proxy for nutrition quality), to the ischemic mortality rate. Since the existing research works on this field, suffer from the proper model testing, we analytically present all the tests necessary to justify the reliability of the result obtained. For this purpose, after specifying and estimating the model, we applied the specification error test, the linearity, multicollinearity and heteroscedasticity tests, the autocorrelation and stability tests and the ARCH effect test. Finally, we present the aggregate effect of the above socioeconomic factors. In brief, we found that an increase of cigarettes smoked, of fat and alcohol consumption and the number of passenger cars will result to a relevant increase regarding mortality. The latter one is also affected by the changes in unemployment rate. On the other hand, an increase of personal disposable income may negatively affect mortality, by almost the same portion.

A vast amount of papers is published every year about species evolution, the most interesting being those recently published in the journal "Nature", concerning the human-ape relationship. The results and the new theories generated from this research are sometimes astonishing, raising not only biological, but also social, religious and cultural questions. One of the new questions concerns the role of species interbreeding as a means of evolution. In the subject of species interbreeding between human and ape we found some interesting historical and mythical information that sort of back-up this theory of interbreeding, with a historical and cultural side view.
